Where is the chemical composition of NM450 BBN company
It has good toughness. By strictly controlling the chemical composition, reducing the content of chemical composition of NM450 harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, chemical composition of NM450 using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.
Nickel element is mainly used to form and stabilize the austenite structure, so that the chemical composition of NM450 steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
The company's main steel plate varieties: chemical composition of NM450, boiler pressure vessel plate, low-alloy plate and high-strength plate, bridge plate, alloy plate, carbon steel, wear-resistant plate, pipeline steel, nuclear power steel, wind power and hydropower steel, ship plate, building structural steel, Die steel, military steel plate, hydrogen steel plate and various special steels, etc.
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in chemical composition of NM450 etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
